3 Responses to Why is the hippo called a ‘river horse’?

You bet they're quick! Hippos can reach speeds of up to 30 mph (48 kph) on land, and can even run as fast as a man can walk while under water. Bring it on Mr. Usain Bolt, you still have a bit of workout to do! 🙂

NB: Just to give you an idea, Usain Bolt ONLY runs at 37.57 kph. Easy peezy, run this in my sleep! 😉
